To all whom it may concern ourt Markers, of which. the

Be itkn'own that I, Anonrn JOHNSON, a citizen of the United 'Statcs of America, and a resident of Montclair, county of Essex, and State of New Jersey, have invented certain new and useful llnpi'rovements in Tennis: following is a repecificatioinl I The object otthis invention is to provide a. tcnnl rcourt marker of simple and durable construction. which is easily operated, and which will deposit marking fluid in'an even clean and clear out line.

In the accompanying sheet of drawirng'sv which formsa part of this application Figure 1 is a perspective of a tennis-court marker embodying my invention, parts-being broken away. F ig. 2 is a perspective of the ozzlc and trough drawn to a larger scale.

it receptacle-l, adapted to contain marking fluid such as finely powdered lime in suspension in water, is carried by a running or hearing. gear and handle. The running gear con'iprisesrunning wheels 2 2'- carried on an axle rod 3, the. rod being secured by straps e d to. a cross bar 5. Upwardly extending from the cross bar is a handle 6. Sui-mounting the handle is a hand-piece 7.

leg 8 depends from the handle and reachesl 'l' in ashort distance of the ground when the handle is held at the angle at which the marker is operated, so that with but slight additional. tilting of the handle the 1 "l e t tli' d D d' 1.0, w1.. r-s on e groun epen mg trom the receptacle 1s a rlgld pipe 9 contain? controlling valve 10 and supporting lower end a nozzle 11. A trough 12 to the forwardsido ofthe nozzle ends rearwar'dly and downwardly ms-r the nozzle so that the rent end trails the trough into a-plurality of chair- "l the nozzle is provided with sepa- 14% 14- so located with respect to into a different channel. From the o urolling valve a rod 15 connected thereis carried upwardly along the right side of thehandie and the upper end is bent laterally where it will be Within reach of the right hand of the operator While his ha; are in placcon the hand-piece for propelling the apparatus. The rod engages Y with a gage it which is carried by the l1andpiece and is provded with notches constituting a plurality ut' gage points: The conround. A series of partitions 13 13 iaunels that each delivers the marking A spring 17 retracts the rod when it is released from the gagenotches and closes the valve. A second rod 18 is carried along the rear end of the trpugh to which it is at taohed, and at its upper end is bent laterally of the operator at the hand-piece 6f the handle. the groundwhen the rod is drawn against the hand-piece. A strainer 19 is fitted to the i which is not finely divided from being put into the receptacle. A splash board. 20 prevents any fluidfrom being thrown out at the recepta e and is capped at the top but is notched at 21 at the side thereby prosettling will not accumulate in the pipe.

In the operation of marking a tenniscourt the apparatus is held at about the angle illus'tratedand propelled over the line" to be marked with the valve open and its controlling'rod latched in the gage notch which is found togive the proper flow for the desired strength ofmark'. In marking where theground is notlevel but is lower at one side than the other the artitions between the channelsin'. the troug prevent any flow on the downhill side in excess of the flow on the otherside. The trough also serves as a shoe to smooth the ground ahead of the deposit and the fluid does nottouch the ground until. the trough has entirely passed so that wet loose earth under the fresh mark will not be stirred upand the clearness of the mark impaired. When it becomes necessary to back the apparatus, as 11 bringing it into'place to mark a second llne, the valve isolosed and the trough is lifted clear of the ground without removing either hand from the hand-piece. i

What I claim as new, and desire to secure by Letters Patent of the United States, 1s

1. In a tennis-court marker, in combination a receptacle adapted to contain marking fluid, a supporting. running gear and handle, a trough with an impervious bottomadapted to trail on the ground, and a nozzle through which marking fluid is delivered from the receptacle into the trough.

This serves to lift the trough oli' top of the receptacle and prevents any limethe top in case the machine is jolted. The outletpipe projects through the bottom into vidinga side entrance only so that lime in" nection to the valve is such that it will be opened more or less accordingly as the rod' is engaged with a higher or lower notch.

left side of'the handle from a point near the c where it will be within reach of the left hand 2. In a tennis-court marker, in combination a receptacle adapted to contain marking fluid, a supporting running: gear and handle, a trough adapted to trail on the ground, a nozzle through which marking fluid is delivered fronrthe receptacle into the trough, and a rod connected with the trough and lying along the side of the handle ,whereby the trough may be lifted from the ground. o

3. In a tennis-court marker, in combine tion a receptacle adapted to contain marking fluid, a supporting running gear and handle, a nozzle through which marking fluid is delivered, a controlling valve between the nozzle and receptacle, and a rod connected with the valve and lying along the side of the handle, and a gagewith a plurality of gage points by which the valve may be set,

4. In a tennis-court'in arl er, in co1nbination a receptacle adapted'to contain marking fluid, a supporting running gear and handle,

a trough with an impervious bottom adapted to trail on the ground, a nozzle through which marking fluid is delivered from the receptacle into the trough, a controlling valve between the nozzle and receptacle, a rod connected.

with the trough andlying along the side of gage points by which the valve may be set,

v 5. In a tennis-court marker, in combination a receptacle adapted to contain marking fluid, a supporting running gear and handle,

a trough having a plurality of channels and adapted to trail on the ground, and a nozzle with separate orifices through which marking fluid is delivered from the receptacle lnto each channel.

6. In a tennis-court marker, in co1nbina tion a receptacle adapted to contain'niarlring fluid, a supporting running gear and handle, a nozzle through which marking fluid. is delivered, a rigid pipe connection between the nozzle and receptacle, and a trough hinged to the nozzle and adapted to trail on the ground.
